    Deal with join points with RULES
    
    Trac #13900 showed that when we have a join point that
    has a RULE, we must push the continuation into the RHS
    of the RULE.
    
    See Note [Rules and unfolding for join points]
    
    It's hard to tickle this bug, so I have not added a regression test.
